Safety of Anthrone. I found the field of Polymer Science very interesting. Saw the article Synthesis and characterization of novel polyimides based on 10,10-bis[4-(4-aminophenoxy)-3-methylphenyl]-9(10H)-anthrone published in 2020, Reprint Addresses Zhong, M; Huang, ZZ (corresponding author), Jiangxi Normal Univ, Key Lab Funct Small Organ Mol, Minist Educ, Nanchang 330022, Jiangxi, Peoples R China.. The CAS is 90-44-8. Through research, I have a further understanding and discovery of Anthrone.
10,10-Bis[4-(4-aminophenoxy)-3-methylphenyl]-9(10H)-anthrone, as a novel aromatic diamine, was synthesized from anthrone by three-step process. A series of polyimides containing methyl substituents and 9(10H)-anthrone pendant groups was prepared from this diamine with various aromatic dianhydridesviathe poly(amic acid) (PAA) precursors and subsequent thermal or chemical imidization procedure. Inherent viscosities of PAAs are between 0.87 and 1.58 dL/g, and the corresponding polyimides have the weight-average molecular weight and number-average molecular weight in the range of 49,400-64,200 and 28,700-37,700, respectively. Most of the polyimides obtained through the chemical cyclodehydration method are soluble in NMP, DMF, DMAc, Py andm-cresol at room temperature. These polyimides have glass transition temperatures of 289-313 degrees C, 10% weight loss temperatures of 484-524 degrees C, char yields of 55-63% at 800 degrees C, and temperature at the maximum-rate degradation of 560-584 degrees C in nitrogen, respectively. The polyimide films obtained through the thermal imidization have tensile strength of 76.43-119.74 MPa, elongation at break of 6.93-12.33%, and tensile modulus of 1.91-2.38 GPa.
